Hello, I recently started seeing red fluid under my 2001 LX470. I took it to the dealer and was informed the oil transmission cooler line was loose. The dealer tightened the line. All was well for a few days and then today I noticed more red fluid under the vehicle. The mechanic told me if the tightening did not work, the radiator will need replacing. Has anyone had this problem before? If yes, what course of action did you take? I am handy so I think I can replace the radiator. However, I would like to get some thoughts from you all to see what I may be getting myself into. Thanks in advance for your responses.
